Answers:    You hold a lot of things to factor within if you are putting foundation down for a house. Are you putting in plumbing (water and sewer). These areas stipulation to be measured out perfectly....also you requirement to prepare the ground under the slab....desires a good bottom. You also need to be paid it thicker on edges and also have some deeper trenches crossing the insides ( call beams ). Concrete needed is measured contained by yards...not weightiness. A square yard of concrete is equal to a 3 foot cube. So if you digit in depth of trenches and a mass of about 5 inches on the rest of slab...your looking at around 4 - 5 yard...give or hold because of size of trenches.
850 sq.ft of floor at 4 in. is going to be 10.5 yds...nickname in a truck...
